The impact of communication can also be measured. Research shows that clear and consistent communication is closely linked to trust, engagement and organisational performance. McKinsey’s Global Survey back in 2021 found that organisations were eight times more likely to report a successful transformation when senior managers communicated openly about the progress of change.  

This becomes even more relevant when we consider the employee perspective. Gallup’s 2026 Employee Engagement Strategies found that 29% of employees felt they lacked clear, honest or consistent communication from their leaders, particularly around decisions and organisational change. 

These findings reinforce an important point: communication is not simply about keeping people informed or making them feel included. When people understand what is happening, why it matters and where they fit into the bigger picture, they are better placed to contribute with confidence. Effective communication can therefore influence trust, engagement and how successfully an organisation moves its people towards a common goal. 

However, communication is not just about giving instructions or passing information down the line. It is a two-way process. Leaders need to listen just as much as they speak. Employees want to know that their views matter and that they can raise concerns, share ideas and ask questions without fear of being dismissed. Sometimes, the people closest to a problem are also the ones who can offer the most practical solution. A leader who listens creates space for those conversations to happen. 

This is also where communication connects with areas such as psychology, emotional intelligence and organisational behaviour. Different people interpret information differently. They bring different experiences, personalities, expectations and concerns to the workplace. Effective leaders need to understand their audience and recognise that communication is not simply about what they say, but also about how the message is received and understood. The same message may need to be communicated differently depending on the situation and the people involved. 

Communication also plays an important role in building trust. People are more likely to trust leaders who are open, consistent and honest with them. This becomes even more important during periods of change or uncertainty. Silence can easily create speculation, while poor communication can lead to misunderstanding and resistance. Leaders may not always have all the answers, but communicating what is known, acknowledging what is not yet known and keeping people updated can make a significant difference.

It is useful to look at what happens when this communication breaks down. When people do not receive enough information, they often fill in the gaps themselves. Different versions of the same message begin to circulate. Assumptions replace facts. Employees may become uncertain about what is expected of them, resulting in repeated questions, duplicated work, mistakes or delays.

These may appear to be small issues individually, but over time the penalty for poor communication can become much greater. It can lead to declining trust, disengagement, strained working relationships, resistance to change, higher turnover and even reputational damage. In other words, poor communication carries a cost, even when that cost does not immediately appear on an organisation’s balance sheet.

Consider a simple workplace scenario. An organisation is undergoing a major restructuring that will affect employees across several departments. One leader sends an email announcing the changes with very little explanation and provides no opportunity for employees to ask questions. Another leader explains why the restructuring is necessary, acknowledges that people may be concerned, shares what information is currently available and creates an opportunity for employees to raise questions.

The organisational decision may be exactly the same in both situations, but the employee experience can be completely different. One approach may create uncertainty, speculation and resistance. The other may not remove every concern, but it can create greater understanding, trust and willingness to move forward. The difference is not necessarily the decision itself. It is how that decision is communicated.

Communication also shapes organisational culture. The way leaders speak to people, respond to mistakes, give feedback and recognise contributions sends a powerful message about what the organisation values. If leaders expect openness, collaboration and respect from their teams, they need to demonstrate these qualities themselves. People often take their cues from what leaders do, not simply from what they say.

Today, communication is perhaps even more challenging because we communicate across so many different platforms. Emails, WhatsApp messages, online meetings and digital tools may make communication faster, but faster does not necessarily mean better. A message can be delivered instantly and still be misunderstood.

This requires leaders to exercise judgement. They need to know when an email will do, when a face-to-face conversation is necessary, when a team needs more context and when someone simply needs to be heard. Technology can make communication more efficient, but it should never replace the human element that builds understanding and trust.

This is particularly important as organisations become more digital, diverse and interconnected. Leaders may now be communicating across departments, generations, cultures and even geographical locations. The ability to adapt how we communicate while keeping the message clear and consistent has therefore become an increasingly important leadership competency.

For me, this is why communication is not simply another leadership skill. It is the mechanism that connects vision to action, strategy to execution and leaders to their people. Its effectiveness can ultimately be seen in how well people understand their roles, how confidently they contribute, how they respond to change and how much they trust those leading them.

A strategy means very little if people do not understand it. A vision cannot inspire if people cannot see where they fit into it. And change becomes much harder when people do not understand why it is happening.

At the end of the day, leadership is not just about having people follow you. It is about bringing people with you.

And whether people choose to come with you often depends on how clearly you communicate, how genuinely you listen and how much they trust what they hear.
